Casement window mounted air conditioner



evaporator, the compressor and other usual e1e ments of the system in the customary way. It is deemed unnecessary for the purposes of the present disclosure, to detail the refrigeration system as it involves no departure from common practice in the refrigeration art. It may be pointed out, however, that the tubes 52 and 53 leading from the compressor to the condensor, must necessarily take a circuitous path through the compartments [8 and 19, due to the presence of the slot or space ioetween the housings of the condensor and. the compressor. As shown by way of example, the said tubes pass through the opening 31 between the wa1ls and 39.

T0 effect installation of the improved cooling unit or air conditioner of the present invention,

it is necessary on1y to look the window sashes 6 and 8 in the c1osed position, remove the g1ass from the lowermost 1ights of the sashes, and s1ide the unit through the openings previously occupied by the g1ass panes, With the mullions '21 and 22 occupying the space 2 between the divided or separated housings I8 and I9. The wa1l 25 at the base of the slot may substantially contact the mullions, and where the unit housing contacts the window sashes a suitabie seal may be furnished for the purpose of excludng i11- sects, dirt, and other foreign substances from the room. As suggested by Fig. 4, a sea1 might be eiected ioy means of a flange 49 applied about the unit and perhaps equipped with a suitabie gasket te bear against the sashes. when necessary, can be provided in varous ways. It will at once be appreciated that the installation is eflected quickly and With 1ittle effort and inconvenience, thereby saving time and labor expenses. The unit may receive its support from the window si11, wholly or partially.

It is a matter immaterial to the invention, Whether the flow of air is as indicated upon the drawing, or reversed as to the direction of flow. 'Ihis may depend iargelyupon the type of fans or blowers empioyed in the system, or upon the location thereof. The various ports or the intake and delivery of air may be located otherwise than as shown in the exampie illustrated by the drawing. For example, the ports 40 er 4! may be located in the top wa1l of the evaporator housing 11, or the ports and. of Fig. 3 may be located in the sides or bottom walls of the husings 18 and I9.

Various ether modifications and changes in structural details of the device may be made, within the scope of the appended claims, without departin from the spirit of the invention.
